Royal Flemish glass was a line of art glass made by the Mt. Washington Glass Works in New Bedford, Massachusetts. This line was designed to look like stained glass. The line was made during the late 1880s. The pieces normally feature a colored satin glass decorated with dark colors and raised gold designs. The glass was patented in 1894.
A piece of this art glass was featured on Antiques Roadshow, Dallas, Hour 3 and was appraised for $5000 – $7000.
